摘要： 针对辽河油田直井注蒸汽开采超稠油油藏效果差的实际情况, 利用最新研制的水平井热采数值模拟软件———NUMSIP-4 软件, 研究了杜84 块不同水平井布井方式和开采方式的开发效果。结果表明, 该块最佳开采方式为蒸汽辅助重力驱, 并采用成对水平井组合,上注下采, 水平段长300 m,注采井距15 m的布井方式。该项研究成果可以为类似超稠油油藏的开发所借鉴。

Abstract: Steam injection of super viscous oil reservoir by utilizing a vertical well performed unsatisfactorily in Liaohe oilfield.The use of the newly-developed horizontal well thermal recovery simulator NUMSIP-4 in the investigation of the production performance of horizontal well at different well patterns and recovery methods in Block Du 84 showed that the optimized recovery method is steam assisted gravity drainage, combined with paired horizontal wells with injection from the upper one and production from the lower one, horizontal length of 300 m and injection-production well spacing of 15 m.It may be used in the development of similar reservoir for reference.
